Callaway Women's XR 16 Driver Forgiveness meets fast from our most aerodynamic head shape and a speed step crown: we worked with the aerodynamics experts at boeing to reach a completely new threshold of ball speed Extreme forgiveness: this driver is extremely forgiving, and that's what happens when you develop a larger shape for MOI, stretch out the crown with a bigger footprint, and put in a center of gravity that's lower and deeper Even more ball speed with a faster face: we've stepped up our game with Next generation RMOTO face Technology that's 9 grams lighter and thinner and the body is lighter too, which leads to more ball speed across the face An even stronger face: that's right, we've made the face even stronger with new 8-1-1 titanium. When you combine the faster face with the extreme forgiveness in this driver, you can pick up a lot of ball speed, wherever the ball hits the face
